Someone want to inform me what the difference between "Noiseless" and "Silent" is? Their own little made-up graph even takes a huge hike between the two.

At £70 inc vat, which appears to have been recently cut from £80, the ZM460-APS is far from cheap, its silence is in fact golden in more ways than one. The Globalwin Super Silent 450W, Akasa Ultra Quiet 460W and Tagan 420W Whisper Quiet PSU all come in at nearly £20 cheaper than the ZM460-APS and claim to be silent or thereabouts.

also measuring with motherboard moniters is not good testing ...

Review sites have to recreate the testing environment exactly as it was for every review, and it is impossible to do so unless you have a chamber to do the testing in. This is why a subjective report on sound levels is more useful in this case.

Another non-visible difference is the inclusion of a 92mm PWM fan for the CNPS9500-AT, allowing the motherboard to control the speed of the fan according to the temperature of the CPU, which is essential to keep noise at a minimum during low processor usage.
